Malaria Control Strategies

Steps:

• Identify vector control: Statement 1 uses insecticides to eliminate mosquitoes, reducing transmission.
• Identify physical barriers: Statement 2 employs netting to prevent mosquito bites on humans.
• Identify chemoprevention: Statement 3 involves drugs that inhibit Plasmodium development in people.
• Confirm all methods: Each targets different aspects of malaria lifecycle per WHO guidelines.

Why A is correct:

• All three statements align with integrated malaria control, combining vector reduction, bite prevention, and pathogen suppression as defined by global health protocols.

Why the others are wrong:

• B omits drug-based prevention, a core human-side strategy.
• C ignores netting and drugs, limiting to partial vector control.
• D excludes insecticides, neglecting essential mosquito elimination.

Final answer: A
